Cervello, Barcelona, Spain, a Spanish sociedad regular colectiva Application August 30, 1955, Serial No. 531,352 Claims priority, application Spain September 29, 1954 4 Claims. (Cl. 222521) This invention relates to an appliance to be fixed upon the mouth of a flexible bottle for the delivery of a liquid in drops or by atomisation. The invention is essentially characterised by the fact that it consists of a bell, which is adapted to be fixed upon the mouth of the bottle, and which has an aperture in its inner end; a member of elongated form which exhibits an axial cavity or passage, and which, at one of its ends, terminates in the form of a disc, which is pressed against the inner end of the bell, constituting a fluidtight closure therewith when its elongated part is passed through the aperture in the top of the said bell; and a bell-shaped cap, to be screwed on to the elongated part of the member previously indicated, constituting a fluidtight closure therewith. The said elongated members as has been indicated, exhibits an axial passage, which, through either a radical duct or a duct coaxial with the passage, establishes communication between the interior of the bottle and the interior of the cap.

Likewise in the inner end of the said bell-shaped cap, or in a radial direction in the cap, there is a duct which establishes communication between the interior of the cap and the exterior, the ducts in the elongated member and in the cap being arranged in such a way that when the cap is screwed right home on to the elongated member, the conduction of the elongated member in communication with its axial discharge passage is obstructed.

The invention is clearly illustrated in the accompanying drawing, in which:

Figure 1 is an axial sectional elevation of one form of the invention,

Figure 2 is a similar view of a second form of the invention, and

Figure 3 is a similar view of a further modification of the invention applied to a bottle.

As the figures show, the apparatus comprises a bell 1, to be screwed on to the outside of the neck of the flexible bottle A. This bell has an aperture in its inner end.

The apparatus also includes a member 2 of elongated form, which, at one of its ends, terminates in the form of a disc, which is pressed against the inner end of the bell 1, constituting a fluidtight joint therewith, when its elongated part is passed through the aperture in the top or inner end of the bell. An axial discharge passage 4, in communication with the interior of the bottle, provided in the central portion of the elongated member 2, is in communication with a duct co-axial 5 (Figure 1) or a radial duct 5' (Figure 2), provided in the elongated member 2, which establishes communication with the interior of a bell-shaped cap 3.

The bell-shaped cap 3 is internally screw-threaded, to enable it to be screwed on to the outside of the elongated member 2 and to constitute a fluidtight joint therewith. The said cap 3 has in its inner end or in its side wall a duct 6' (Figure 2) or a duct 6 (Figure 1), which establishes communication between the exterior and the interior of the bell-shaped cap 3.

Under these conditions it is obvious that upon the cap 3 being screwed right home on to the screw-threaded part of the elongated member 2, the duct 5 or 5' of the said elongated member will be obstructed by the cap 3. When the cap is partially unscrewed, on the other hand, as indicated in the drawings, upon the assemblage being inverted the liquid contained in the interior of the bottle will enter the axial discharge passage 4, and, through the duct 5 or 5, will reach the interior of the bell-shaped cap 3, to issue to the outside through the duct 6 or 6' provided in the said cap. Hence the liquid contained in the bottle will escape in the form of drops when the bottle is gently squeezed.

From what has been set forth it will be understood that without going beyond the limits of the present invention, it will be possible to obtain the discharge of the liquid with atomisation, by merely coupling to the axial discharge passage 4 of the elongated member 2 a small tube 4 as shown in Figure 2 which penetrates into the body of the liquid contained in the flexible bottle A. In this way, by the deformation of the bottle, the discharge of the liquid to the exterior will be obtained in a completely atomised state, whenever there is no fluidtight closure between the axial discharge passage 4 and the little tube 4 coupled thereto. Atomisation will also occur when the bottle without the draft tube is inverted and squeezed tightly so that the bottle contents are subjected to a high pressure. For atomisa-tion, however, it is more preferable to use the draft tube.

It will be understood from what has been set forth that modifications may be made in all those details of construction of the apparatus which do not influence its essential nature. It will therefore be possible for it to be made of any size, and of any material or materials that may be found convenient; and it is applicable to any type of flexible or deformable bottle.

I therefore claim:

1. An atomizing closure for flexible bottles, or the like, comprising a cap adapted to be secured to the bottle neck, an aperture through the end of said cap, an elongated member terminating within the cap in. a disc forming a seal with the bottle neck, an axial discharge passage extending through said disc and substantially to the free end of said elongated member, a first small discharge duct extending from the end of said axial discharge passage to the end of said elongated member, screw threads on the outer surface of said elongated member, a screw cap mounted on the end of said elongated member and engaging said screw threads, and a second small discharge duct in said screw cap out of alignment with said first duct whereby upon screwing said screw cap tight one of said ducts is blocked by contact between said screw cap and the end of said elongated member.

2. The closure of claim 1 in which said first discharge duct extends coaxially with said elongated member and said second discharge duct extends radially with respect to said screw cap.

3. The closure of claim 1 in which said first discharge duct extends radially of said elongated member and said second discharge duct extends co-axially of said screw cap.

4. A closure as claimed in claim 1, characterised by the provision of a small tube, which is coupled to the axial discharge passage of the elongated member without constituting a fluidtight closure therewith, and which penetrates into the body of the liquid contained in the bottle.
